Description

PATENT OFFICE.
WILHELM KLAPPROTH, OF OBER-INGELHEIM, GERMANY. I
BAKING-POWDER.
No Drawing.
To all whom it may concern:
Be it known that I, VVILHELM KLAPPROTH, a citizen of the Empire of Germany, and residing at Ober Ingelheim on the Rhine, Grand Duchy of Hesse, Germany, have 1nvented certain new and useful Improvements in Baking-Powder, of which the following is a specification.
My invention relates to baking-powder which principally consists of an alkali or earth-alkali bicarbonate or carbonate, preferably bicarbonate of soda, and an aluminium salt of lactic acid.
Attempts to employ lactic acid, which is beneficial to the human body, instead of the but little beneficial tartaric acid as the acid constitutent of ltraking' powder mixtures have heretofore failed owing to the bakingpowder mixtures obtained withlactate salts not having the requisite stability. All lactates heretofofe investigated for this urpose, particularly the acid lactate of lime, when mixed with bicarbonate of soda, even when the mixture was made very carefully and with perfectly dry materials, very soon caused carbonic acid to be split ofi even when they were preserved at an ordinary temperature and also had a diminished raising power. After a relatively short time these baking-powder mixtures became u11- usable. Owing to the ready solubility of the other, better-known lactates the possibility' of making a stable lactic acid baking-powder seemed hopeless, especially as the soda and potash salt of lactic acid, because liquid, cannot be employed at all as ingredients of baking-powder.
After numerous trials I have succeeded in discovering in aluminium lactate a lactate which, in combination with carbonates and bicarbonates, forms a thoroughly stable baking-powder mixture. During a time of observation extending over several months no diminution of carbonic acid could be observed in a baking-powder mixture made of lactate of aluminium and bicarbonate of soda and kept in an open bowl.
When employed for baking-powder purposes, aluminium lactate has the great ad- Specification of Letters Patent.
Application filed May 1, 1912. Serial No. 694,362.
Patented May 6, 191 3.
vantage, as compared with the lactates employed heretofore for similar purposes, that the relatively costly lactic acid is fully utilized. The conversion takes place, for example, in the case of normal aluminium lactate and bicarbonate of soda according to the following formula:
- From this it is seen that when employing the aluminium salt. all the acid bound to the aluminium is used for producing carbonic acid.
My new baking-powder can have its properties increased or modified by snitableadmixtures and filling agents.
Instead of bicarbonate of soda other bicarbonates and carbonates, such as calcium carbonate for example, may be used. It has also been found that stable baking-powders also with the basic, aluminium salt.
I claim 1. Baking powder composed substantially of a lactate of aluminium and a suitable substance which yields'carbonic acid when reacting with the lactate.
, 2. Baking-powder composed substantially of normal lactate of aluminium and a suitable substance which yields carbonic acid when reacting with the lactate.
3. Baking-powder composed substantially of a lactate of aluminium and an alkali earbonate.
l. Bal ing-powder composed substantially of a lactate of aluminium and an alkali hicarbonate.
5. Baking-powder composed substantially of a lactate of aluminium, a suitable substance which yiclds carbonic acid when reacting with the lactate, and a filling agent.
In testimony whereof, I aflix my signature in the presence of two witnesses.
